The invention provides a motor and a rotation control method, and in order to make the purpose, technical scheme and effect of the invention clearer and clearer, the invention is further described in detail below by referring to the attached drawings and taking examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, fig. 2 and fig. 3, fig. 1 is a perspective view of a motor according to an embodiment of the present invention. Fig. 2 is an exploded view of the motor shown in fig. 1. Fig. 3 is a cross-sectional view of the motor shown in fig. 1 through the axis of the screw. As shown in fig. 1, 2 and 3, the motor 101 of the present invention includes:
the structure comprises a screw 202 provided with a threaded part 214, a rear cover 206 provided with a first round hole 215, a function conversion block 213 provided with a second round hole 208, a stator 211 and a rotor 212 which is arranged in the stator 211 in a penetrating manner and is provided with a threaded hole 209, wherein the rear cover 206 is fixedly connected with the stator 211, the function conversion block 213 is arranged in the rear cover 206, and the screw 202 sequentially penetrates through the first round hole 215, the second round hole 208 and the threaded hole 209;
a plurality of elastic supporting structures arranged on the rear cover 206, wherein the elastic supporting structures are used for supporting the function conversion block 213 and generating resistance for preventing the function conversion block from rotating at the contact position of the elastic supporting structures and the function conversion block;
a limiting protrusion is arranged in a circular hole of the function conversion block 213, a limiting groove matched with the limiting protrusion is arranged on the screw 202 along the axial direction of the screw, the depth of the limiting groove is greater than the thread height of the thread part, when the limiting protrusion is matched with the limiting groove, the rotor 212 and the screw 202 are prevented from rotating relatively, so that the screw 202 moves axially, and when the rotor 212 rotates and is static relative to the screw 202, the function conversion block 213 is driven to rotate along with the screw 202;
the threaded portion 214 is disposed corresponding to the threaded hole 209.
It should be emphasized that, the technical scheme adopted by the invention is to arrange the limiting groove on the screw rod, so that the screw rod is enabled to move along the axial direction of the screw rod when the rotor and the screw rod rotate relatively, and the mode for realizing the function is various and is not limited to arranging the limiting groove.
The elastic supporting structure is mainly used for supporting the function conversion block 213, and resistance for preventing the function conversion block from rotating is generated at the contact position of the elastic supporting structure and the function conversion block 213. In this embodiment, the motor is provided with a threaded hole structure 207 on four side walls of the rear cover, and an elastic supporting structure is arranged in each threaded hole structure 207, and the elastic supporting structure includes a steel ball 205, a spring 204 and a set screw 203 which are arranged in sequence from inside to outside. Resistance against rotation of the function conversion block is generated at the position where the steel ball 205 contacts the function conversion block 213, and this resistance is static friction therebetween (which is generated only when the function conversion block has a tendency to slide with respect to the steel ball). In order to increase the resistance, the invention provides a preferable scheme, as shown in fig. 5, a circular clamping groove 502 is arranged on the outer side of the function conversion block, and a steel ball supported by a spring is placed in the circular clamping groove 502. It should be noted that, after the circular slot 502 is provided, the resistance between the steel ball and the function conversion block changes, and the resistance includes not only the static friction force generated by the pressure, but also the blocking force provided by the component force of the pressure in the rotation direction. Under the condition of arranging the circular clamping groove 502, only when the acting force of the function conversion block 213 on the steel ball 205 is large enough, the steel ball 205 presses the spring 204 to deform, so that the steel ball retracts, and the function conversion block 213 and the steel ball 205 rotate relatively.
For the position-limiting protrusion and the position-limiting groove respectively disposed on the function conversion block 206 and the screw 202, the present invention provides a preferred embodiment, specifically referring to fig. 4 and 5, fig. 4 is a partially enlarged view of a position a in fig. 2; fig. 5 is a cross-sectional view of a functional conversion block according to the present invention. As shown in fig. 4, the screw portion of the screw 202 is provided with a limit groove, which is specifically a limit groove 401 arranged on the screw 202 along the axial direction of the screw, and the depth of the limit groove is greater than the thread height of the screw portion. As shown in fig. 5, the function conversion block 203 is provided with a limiting protrusion, specifically, the limiting protrusion is a limiting protrusion 501 arranged in the second circular hole of the function conversion block. As can be seen from fig. 3, the limiting protrusion is disposed in the limiting groove, so that when the rotor 212 rotates relative to the screw 202, the screw 202 is prevented from rotating and the screw 202 moves axially, and when the rotor 212 rotates and is stationary relative to the screw 202, the function switching block 206 is driven to rotate along with the screw 202.
The present invention provides a plurality of embodiments, and specifically, referring to fig. 7, 8, 9 and 10, fig. 7 is a perspective view of a motor according to another preferred embodiment of the present invention, fig. 8 is an exploded view of the motor shown in fig. 7, fig. 9 is a cross-sectional view of the motor shown in fig. 7 through the axis of the screw, and fig. 10 is an enlarged view of a function switching block shown in fig. 7. As shown in fig. 7, 8, 9 and 10, the present embodiment is substantially similar to the embodiment shown in fig. 2, except that the original structures of the function conversion block 213, the screw 202, the rotor 212 and the rear cover 206 are changed, specifically, a groove 706 with a circular arc-shaped cross section is arranged in the circular arc direction of the outer side wall of the function conversion block 213, the circular hole groove is adapted to the steel ball, so as to reduce the friction between the function conversion block and the steel ball, further reduce the abrasion of the function conversion block to the steel ball, so that the service life of the steel ball is longer, and a limit protrusion 1001 (as shown in fig. 10) is arranged in the circular hole of the function conversion block 213; the two ends of the threaded part of the screw 202 are respectively provided with a first gasket 702 and a second gasket 703, the first gasket 702 and the second gasket 703 are both circular, and the gaskets are arranged to prevent the rotor from continuing to rotate forwards (relative to the screw) when the rotor reaches the two ends of the screw, so that the threaded structure in the threaded hole of the rotor cannot be damaged; the rotor 212 adopts a straight cylinder shape; the round hole 704 is enlarged on the rear cover 206, so that friction between the rear cover 206 and the first gasket 702 arranged on the screw 202 can be avoided, contact between the screw 202 and the rear cover 206 can be avoided, meanwhile, the contact area between the upper surface of the function conversion block 213 and the rear cover 206 can be reduced, friction is reduced, and mutual abrasion between the two is reduced. The preferred embodiment is improved on the basis of the embodiment shown in fig. 2, so that the components of the motor are reasonably matched and can better exert respective functions, for example, the arranged arc-shaped groove increases the contact area with the surface of the steel ball, so that the abrasion of the steel ball is uniformly distributed, and the service life of the steel ball is indirectly prolonged.
It should be emphasized that the elastic supporting structure of the present invention is not limited to the steel ball, the spring and the set screw, but may be an electric structure. If the electric structure comprises an electromagnetic valve, the steel ball supports the function conversion block under the condition of power failure, the magnetic attraction of the steel ball is generated under the power-on state, the steel ball is separated from the function conversion block, and the function conversion block is not supported any more.

The screw rod rotates: the screw rod and the function conversion block can not rotate relatively, and the function conversion block rotates along with the screw rod when the screw rod rotates, namely, as long as the function conversion block can rotate, the screw rod can rotate along with the screw rod, so that the function conversion block rotates only by ensuring that the force between the screw rod and the rotor is greater than the resistance provided by the elastic jacking structure, and if the steel ball is returned. The screw rod is provided with the threaded part, preferably, the threaded part is arranged at one end of the screw rod, and the width of the threaded part is larger than the hole length of the threaded hole. One end of the threaded part of the screw is provided with a nut. As is known, the thread of the thread part has upper and lower limits, and when the thread hole is at the upper and lower limits of the thread part, the thread hole can not rotate relatively, at the moment, a very large force can be generated between the thread part and the thread hole, the force can be larger than the resistance between the elastic supporting structure and the function conversion block, and the steel ball presses the spring to deform, so that the steel ball returns, and the screw rod rotates.

The position of the rotor and the position of the function conversion block are relatively unchanged, the axial length of the limiting groove is equal to the width of the thread part, when the rotor contacts one end of the thread part, the limiting protrusion can also reach one end of the limiting groove, and the screw thread of the threaded hole is prevented from being damaged by the screw rod. Specifically, as shown in fig. 6, the length of the screw portion of the screw 601 and the length of the limiting groove are both b, when the rotor reaches the end of the screw portion, the limiting protrusion of the function conversion block first reaches one end of the limiting groove on the screw, and the limitation between the rotor and the screw is realized by staggering the limiting groove and the screw thread portion.
The motor is preferably arranged, the upper limit and the lower limit of the threaded portion are respectively provided with a first clamping groove and a second clamping groove, and the first clamping groove and the second clamping groove are used for fixing the rotor when the threaded portion of the rotor reaches the upper limit and the lower limit of the threaded portion, so that threads of the threaded portion are prevented from being damaged.
